Abstract:China is the world"s largest Marine shellfish aquaculture country, aquaculture production has increased rapidly in recent decades, in 2023, the production of 16.460,600 tons, aquaculture area of 1357.53 thousand hectares. Marine shellfish farming in China has made important contributions to increasing fishermen"s income, improving water transparency, alleviating water eutrophication, and actively responding to climate change. However, on the whole, China"s Marine shellfish aquaculture industry is still labor-intensive and quantity efficient industry, and the improvement of aquaculture output depends more on the expansion of aquaculture area. In the past two decades, China"s Marine shellfish aquaculture has increased by 28.11% on the cultivation area and maintained a 54.19% increase in aquaculture output. With the increasingly fierce competition for Marine space resources from various Marine industries such as coastal tourism and Marine transportation, mariculture is increasingly constrained by space. In this context, it is urgent to seek scientific ways to improve the production efficiency of limited space. It is one of the effective ways to enable the industry to improve production efficiency. In many new aquatic varieties, the growth rate is usually one of the important target breeding traits.
